A motor controller is configured to perform positioning of a rotor of a brushless motor immediately when power supply is turned on, and not after actually receiving a target value related to control for the brushless motor from a main ECU, which determines the target value. The motor controller finishes or is performing the rotor positioning, when the target value is received from the main ECU. For this reason, the motor controller can start rotation control for the brushless motor in accordance with the received target value in a short period of time. |
